Claims.

This invention relates to shower cabinets and more particularly to animproved shower cabinet formed from a few separable and interchangeableparts and. sections which can be shipped to the place of use inknockdown condition and assembled at the place of use by unskilled laborand with a minimum of eiiort.

In accordance with this invention, an improved metal shower cabinet ispresented, which can be made from sheet metal, which is sturdy and 1strong in construction, highly attractive in design and appearance, andwhich can be made with a minimum of operations and at minimum cost.

Another object of this invention is to provide an improved showercabinet so constructed that it may be assembled at the plant from aminimum number of parts and which may be interchangeably assembled inthe field by unskilled labor to suit field conditions without specialfittings or screws.

Still another object of this invention is to provide an improved showercabinet formed into sections or units at the plant from a minimum numberof parts, which sections or units may be interchangeably assembled,telescoped and snapped together in the field.

Other objects of this invention will become apparent as the disclosureproceeds.

Various other features and advantages of the,

invention will be apparent from the following particular description andfrom an inspection of the accompanying drawings.

Although the novel features which are believed to be characteristic ofthis invention will be particularly pointed out in the claims appendedhereto, the invention itself, as to its objects and advantages, and themanner in which it may be carried out, may be better understood byreferring to the following description taken in connection with theaccompanying drawings forming a part thereof, in which:

Similar reference characters refer to similar parts throughout theseveral views of the drawings and the specification. 1

Referring to the drawings, this shower cabine comprises a base unit I,interchangeable side wall sections 2 and 3, a rear wall section 4, a topframe member 5 and a curtain hanger 6, which are rigidly assembled atthe plant as individual units ready for quick erection in the field.

The base unit I is formed from only three main.

pieces of sheet metal formed to provide a pan member In supported uponabase frame 20 and an intermediate frame 26. The base frame 20 is formedfrom a single elongated strip of sheet metal of suitable gauge which isbent into generally channel-shaped form, as shown in Figs. 2,

-31 and 5. This channel-shaped sheet'metal strip comprises essentially aside wall forming portion 2| which constitutes the bottom of thechannel, an inturned flange 22 which is to rest on the floor of thebuilding in which the cabinet is installed, and an inturned flange 23upon which the pan l0 seats. The flange portion 22 may be provided withan upturned lip 24 to stiffen and strengthen the base frame. After thechannel section 20 has been formed, it is bent to provide a rectangularframe by cutting V-shaped notches in the flanges 22 and 23 of thechannel at the corners of the frame to provide a mitered joint securedby welding. The meeting ends of the channel-shaped section when bentinto rectangular form are also welded together to provide a sturdy andrigid frame.

The pan member In is also formed from a single piece of sheet metalcomprising a sloping bottom wall 30 which is defined by four slopedtriangular shaped bottom wall portions 31 defined by radiating creaselines which radiate from a central drain aperture 38. The inner ends ofthe triangular shaped portions 31 may be depressed so as to present agenerally depressed circular flange 39 to provide a seat for a suitabledrain cover. The periphery of the bottom wall terminates in upturnedvertical wall portions which form the front wall ll, side walls l2 andI4, and rear wall I 3 of the base unit. The free ends of these verticalwalls are suitably welded together at the corners. The inturned flange23 of the base frame 20 is secured as by spot welding 36 to the bottomwall 30 of the pan adjacent the periphery'thereof. The side wall formingfront wall ll, side walls l2 and i4, and rear wall l3 of the base unit.

The bottom wall of the pan member is reting V notches in the intumedflange 23, the adjacent edges of the V cuts being secured together as bywelding. The ends of the leg portion 21 3 of the 1 frame when bent intorectangular form are secured together. as, by welding, The outi turnedflange 26 of the frame26is'secured to the bottomwalljll of the panmember asby spot f welds 26'. The frame 26 is so shaped that the Iintumed flange 23 thereof will rest upon the floor 1 upon which thecabinet is supported.

The side wall sections 2 and 3 are each fornied from ;a. single piece ofsheet metal and when formed areidenticalin shape. ,Each of the side 1wallsections'2 and} comprises a sidewall panel 3| and an intumed panelportion 32 at each end 1 thereof, Each' intumed panel :portion 32 hasits 1 free edge shaped into tube formation 32" -com-, 1 prising an edgeportion 33 bent at right angles a to panel portion,- a rebent .p ortion34 extends ing generally parallel tothepanel portion 32,

and an intumed lip portion 35 extending in-. 'wardly toward theadjacent, panel portion 32. 1 Each side wall section. is thus providedwith two panel portions 32 having their free side edges bentinto tubeformation. 32' so that either panel portion 32 may be positioned to forma partof therear wall of the cabinet or part of the front wall of thecabinet.

One of the side wall sections 2 is provided with a pair of spacedapertures 90 through which hot 5 and .cold water control fixtures 9|extend. It will be appreciated that the water control fixtures 9| aresuitably connected to hot and cold water piping outside of the side wallsection 2 of the cabinet. Side wall section 2 is also provided with anopening 92 adjacent the top thereof through which a portion of the sprayhead fixture 93 extends, which is also connected to j the water supplypipe.

that since the side wall sections 2 and 3 are iden- 1 tical in form, theside wall section 2 carrying the water fixture openings may bepositioned on either the right hand side or left hand side of It will beappreciated the cabinet, to suit field conditions.

The rear wall section 4 comprises a relatively flat rear panel 4| whichis the same height as the 1 side wall sections 2 and 3 and which is of awidth sumcient to fit snugly between the intumed side 1 portions 33 ofthe adjacent side wall sections. Each side edge of the rear wall panel4| is proj vided with an intumed portion 42 designed to snugly overliethe side portion 33 of the adjacent side wall section, an outturnedportion 43 designedto snugly overlie the edge portion 34 of 1 the sidewall section, and a'rebent lip portion 44 I which extends at an acuteangle with respect to 1 portion 43 so a to frictionally grip the intumedlip portion 35 of the adjacent side wall section. It will be appreciatedthat by bending ,the lip I portion 2| or frame 20 is arranged. so j thatits outside su'iface is substantially in alignment with the outsidesurface of the adjacent portion 44 at an acute angle with respect to theportion 43, this lip portion resiliently grips the adjacent lip portion35 of the side wall section so as to frictionally but rigidly retain therear panel section 4 in fixed upright position. In the construction hereprovided no screws or other securing means are needed to secure the rearwall section 4 to the adjacent side wall sections 2-fand 3. A saving inmaterial and substantially greater speed of erection and demolition arethus realized. 1

1 The rear wall section 4 and each of the side wall sections 2 and 3 areprovided with, spaced angle-shaped clips 56 at the lower end thereof,which are: secured thereto at spaced intervals.

I Each ofthese' clipscomprises a relatively fiat leg portion 51 securedto the adjacent side wall or rear wall section'as by spot welds 58, anoffset portion 59, a downturned leg portion 60, and an outwardly flaredlip portion 6|. Each of the vertical walls It, I 2,13 and I4 of the.base unit carries an angle-shaped bar 60 on the inside face thereofwith which the clips 56 are arrangedto interlock to detachablyisecurethe side and rear wall sections in rigid vertically extending position.Each angle-shaped bar-'50. comprises -a downtumedileg. 5| which is.securedfto, the adjacentvertical wall offthebase unit as.-by spot welds52, an intumed hip portion 53, and. an upturned leg portion 54 whichflisso shaped as tosnuglyLseat against the outside face of the adjacent side,or, rear walisection. .The upwardly extending leg 64 seats within apocket 55 defined between the downturned leg portion '60 of the clip 66and theadjacent outside face of the side or rear wall section. The..clip 56 are formed from sheet metal, generally referred to asv Z-bar inform, ind' may be of almost any length from one inch to-substantially'the width of the side and rearwall section across which it extends.While the bar 5|] preferably extends along substantially theentire-vertical wail of the pan, it also may be 'cut into spacedsections, if desired. v a V a When erected, the-lower edges of the sidewall sections 2 and 3 and rear wall section 4 are designed to seatsnugly against'the inside face of the bottom wall 30 of the pan Hi andare held in spaced relationship from the adjacent vertical walls ll, l2,l3 and I4 of the base unit, which vertical walls are each providedwith-a generally rounded intumed flange portion I5 which has a free edgel6 which abuts the outside face of the adjacent side or rear wallsection. Thus the side wall sections 2 and 3 and the rear wall section 4are rigidly braced and held in fixed erect position by the bracingaction of the edges I6 as well as by the bars 50 interlocking with theclips 56. The intumed flange portion l5 forms with the adjacent verticalwalls ll, l2, l3- and I4 and the adjacent side and rear wall sections anenclosed housing 62 within which the locking bars 50 and the lockingclips 56 are housed and contained. The rounded flange portion l5 of thevertical walls ,I I, l2, l3 and M of the base unit gives the cabinet anattractive and decorative contour which measurably adds to its finishedappearance.

The front wall I l of the base unit, as shown more particularly in Figs.1, 2 and 3, is provided with an intumed tread portion l8 which is formedintegral therewith and which extends between the inturned side portions33 which define the entrance opening into the cabinet. The tread portion3 extends a convenient distance inwardly so as to provide a smooth andcomfortable foot tread. The ends I8 of the tread portion I3 are so cutand formed as to snugly abut the inturned edge portions 33 of theadjacent side wall sections so as to firmly brace the side wall sectionsat the lower end thereof against inward movement. The tread portion I8is pro-" vided with a downturned flange portion I9 which terminates inan outturned lip portion III, which further strengthens and stiffens thetread portion and gives the interior of the cabinet a finishedappearance, free from raw edges which might otherwise cause injury tothe occupant.

The top edges of the sidewall sections 2 and 3 and rear wall section 4are enclosed withina rectangular shaped head frame 5 which is formedfrom a single piece of sheet metal of a generally channel shape incross-section. The sheet metal strip from which the head frame 5 isformed is first bent into the cross-section generally illustrated inFigs. 1 and 3 comprising generally a downturned leg portion III, a topflange portion II bent at right angles to the leg portion II, and arounded embracing flange portion 12. The flange portion II and therounded flange portion 12 are provided with V notches which permit theshaped strip to be bent into rectangular form, the free edges adjacentthe notches being secured together as by welding. The free ends of theleg portion III of the strip are also seecured together by welding so asto provide a rigid rectangular-shaped head frame. It will be noted byreferring more particularly to Fig. 3 that the inner edge 13 of therounded flange portion I2 of the head frame is arranged to abut againstadjacent faces of the side and rear wall sections, so that thesesections are held in rigid rectangular alignment. The leg portion I isalso so arranged as to generally align with the vertical walls II, I 2,I3 and I4 of the base unit positioned therebelow so as to produce asymmetrical arrangement of the parts, free from protruding raw edges,providing a framed appearance for the lower and upper ends of thecabinet having a rounded and attractive symmetry.

To prevent movement of the upper end of the side wall sections withinthehead frame 5, the flange portion II preferably terminates in adownturned lip I4 which is so spaced as to snugly engage the inside faceof the portions 43 of the rear wall section 4 and the portions 34 of theside wall sections adjacent the entrance way to the cabinet. Thedownturned lip portion I4, formed as an integral part of the head frame5, rigidifies the head frame construction and provides means to preventin-bowing of the side and rear wall sections. If further means aredesired to hold the frame in position, paired tongue portions 15 may bestruck out from the inturned flange portion ll of the head frame. Thepaired downwardly extending tongues 15 are so positioned and arranged asto snugly fit within the interior of the tube formations 32' formed atthe free edges of the panel portions 32 of each side wall section. Thedownwardly extending paired tongues I provide abutments which furtherprevent inward movement of the side wall sections 2 and 3 and providemeans for frictionally retaining the head frame 5 in its telescopedposition over the side wall sections and the rear wall section of thecabinet. As further or alternate securing means, tongues 16 may bestruck out from the inturned flange portion II at spaced intervals so asto abut against the inside face of the wall forming panels 3| of theside wall sections 2 and 3, the wall forming panel 4| of the rear wallsection and the wall forming panel 32 of the side wall sections.

It will be appreciated that under normal conditions the downturned lipportion I4 may be amply suflicient to hold the upper end of the side andrear wall sections in rigid rectangular alignment, but if this is notsufllcient the paired tongues 15 or the single tongues 16 or both may beused in conjunction therewith. If the downturned lip 14 is not usedeither the paired tongues I5 or the single tongues It or both may beselectively used as desired.,

A curtain rod Ii, which may be a solid rod or bar or a-hollow tube, issupported by suitable brackets 18 secured to the head frame. Eachbracket 18 may be formed from a stamped piece of sheet metal comprisingan outturned base portion I9 secured as by spot welds to the inturnedtop flange portion II of the head frame in a position to support thecurtain rod 5 and the curtain depending therefrom in convenient positionadjacent the entrance way into the cabinet. A leg portion extendsdownwardly from the base portion, 13 and, as shown more particularly inFig. 2, is provided with a bayonet slot 8I which terminates in adepressed circular seat 82 within which the end of the rod 6 may rest.The curtain rod 6 is of such length as to extend between the side wallpanels 3I of the side wall sections and may be quickly placed insupported position upon the paired brackets I8 when the cabinet has beenerected.

It will be appreciated that a shower cabinet constructed in accordancewith this invention may be quickly formed and assembled at the plantfrom relatively few parts formed into a few separate units or sections.The base pan I0 is formed from a single sheet of metal which can bequickly stamped and bent into the desired shape to form not only thebottom wall 30 of the base unit but the vertical walls II, I2, I3 andI4. The vertical walls where they extend djacent the side wall sectionsand the rear wall section of the cabinet are provided with a roundedinturned flange portion I5 formed by a simple stamping operation. Thefront wall II adjacent the entrance way is provided with a tread portionI8 integral therewith, shaped by a simple stamping operation. Heretoforethe threshold tread has been formed as a separate piece of complicatedconstruction and difficult to attach. The base frame 20 and theintermediate frame 26 are each shaped from a single strip of sheet metaland quickly secured as by spot welds to the bottom wall 30 of the pan.The locking bars 50 extending around the inside face of the verticalwalls II, I2, I3 and I4 of the pan may also be quickly secured to thesevertical walls by spot welds, completing the assembly of the base unit.

The side wall sections 2 and 3 are identical in shape and may be kept instock. Either one of these sections may be provided with apertures and92 to receive the piping fixtures, and they are so shaped as to permitinterchangeable assembly in the field. The side wall sections 2 and 3and the rear wall section 4 are each provided with a series of spacedclips 56 secured thereto as by spot welding and arranged to telescopeover and securely interlock with the adjacent locking bars 50. The rearwall section 4 of the cabinet may be quickly snapped iJtO positionbetween the adjacent panel portions 32 of the erected side wall sections2 and 3. The head frame 5 is applied by telescoping the same over theside and rear wallsections with th n ue 15 in the tube formations}?cfthe side wan "sectionsso asto fixedly ,l ecure the head frame inposition and prevent inward movement of theside wall sections: rod"hanger 6 is, then placed in pomtion, completing erection of the;.clabinet. Plumbing connection to the water-piping and drain outletcanbe convenient-' ly made dueto the interchangeability of the side wallsections} and 8.' r

It will be noted that the improved cabinet herein; disclosed can bequickly assembled and erected in the meld without theapplication ofscrews, fitting of the parts or other time-com sumingerection'operations." The cabinet can be quickly dismantled for storageor erection at an-' of construction, and a highly attractive andsymmetrical appearance. I

While certain novel features .of the invention have been'dis'closed andare pointed out in the annexed claims, it will be understood thatvarious omissions, substitutions and-changes maybe made by thoseskilledin the art without departing from the spirit of the invention. 1
